Ineffective platelet production in thrombocytopenic human immunodeficiency virus-infected patients.
Thrombocytopenia has been characterized in six patients infected with human immunodeficiency virus (HIV) with respect to the delivery of viable platelets into the peripheral circulation (peripheral platelet mass turnover), marrow megakaryocyte mass (product of megakaryocyte number and volume), megakaryocyte progenitor cells, circulating levels of endogenous thrombopoietin (TPO) and platelet TPO...
متن کاملRole of leuCAM integrins and complement in platelet-monocyte rosette formation induced by immune complexes of human immunodeficiency virus-type 1-immune thrombocytopenic purpura patients.
Patients with human immunodeficiency virus-type 1-immune thrombocytopenic purpura (HIV-1-ITP) have elevated polyethylene glycol (PEG)-precipitable immune complexes (ICs) composed of IgG, IgM, and complement that are threefold to sevenfold higher than in healthy control subjects. These complexes contain anti-F (ab')2 as well as anti-idiotype antibodies versus anti-HIV-1gp120. Because anti-F (ab'...
متن کاملHigh Serum Levels of Rheumatoid Factor and Anti-Phosphatidylserine Antibody in Patients with Ischemic Heart Disease
Background: Immunopathological and inflammatory processes play important roles in the initiation and development of Ischemic Heart Disease (IHD). Objective: The aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-small nuclear ribonucleoprotein (anti-Sm), anti-phosphatidylserine (anti-PS) and anti-car...
متن کاملPresence of cross-reactive antibody between human immunodeficiency virus (HIV) and platelet glycoproteins in HIV-related immune thrombocytopenic purpura.
We previously reported the presence in platelet eluates of autoantibodies directed against epitopes of the platelet glycoprotein (GP)IIb/IIIa complex in acquired immunodeficiency syndrome (AIDS)-free human immunodeficiency virus (HIV)-infected patients with immunologic thrombocytopenic purpura (ITP). We investigated whether HIV antibodies recognized platelet membrane antigens to determine wheth...
متن کاملBiologic response to anti-CD16 monoclonal antibody therapy in a human immunodeficiency virus-related immune thrombocytopenic purpura patient.
A patient with refractory human immunodeficiency virus (HIV)-related immune thrombocytopenic purpura (ITP) was treated with 3G8 (anti-CD16) monoclonal antibody on days 1, 3, and 8 (25, 25, and 50 mg were administered intravenously, respectively). Side effects were those expected after the administration of a xenogenic protein, but a severe bone pain occurred from the second injection. At the ti...
